            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran

The code leading to the ICE.

The following code:

SUBROUTINE prtdata(ilen)
INTEGER :: ilen
character(len=ilen), allocatable :: cline(:)
allocate(cline(2))
cline(1) = 'a'
cline(2) = cline(1)
END SUBROUTINE prtdata

leads to an Internal Compiler Error in both 5.4 and 6.1 (and possibly previous
versions.
